RAILWAY-GARDRAFT-RIGGIIQG.

Specification of Letters Patent.

Patented Apr. 11, 1916.

Application filed November 30, 1914. Serial No. 874,642.

clear, concise, and exact description, reference being had to theaccompanying drawings, forming a part of this specification.

' This invention relates to improvements 1n railway car draft riggings.

An object of the invention is to provide a draft rigging for railwaycars of simple and eificient construction and more particularly toprovide a yoke for operating the gear and supporting the same. v

The invention furthermore consists in the improvements in the parts anddevices and in the novel combinations of the parts and devices as hereinshown, described or claimed. i

In the drawing forming a part of this specification, Figure 1 is a partsectional view part sideelevation of a draft rigging, showing myimprovements in connection therewith. Figs. 2 and 3 are verticaltransverse sectional views taken respectively on the lines 22 and 3-3 ofFig. 1 and Fig. 4 is a top plan view of one of the yoke members.

In said drawing, 1010 denote center sills or other draft members towhich are secured front stops 11 and rear stops-12, said stops eachhaving upper and lower flat horizontal surfaces 13 and 14. The frontstops 11 are slotted, as are the sills 10, to receive therethrough acoupler key 15 by which the draw bar 16 is connected to the yoke, moreparticularly hereinafter described.

The improved yoke, as shown in the drawing, comprises two members A A,each of which has upper and lower longitudinally.

extending arms 17 and 18 and which are outwardly turned and fit over andslide upon the horizontal surfaces of the stops whereby the yoke membersA A are supported by the stops. Each member ,A is also provided with avertically extending wall 118 at the front thereof, which is slotted asindicated at 19.

to receive the coupler key 15. At the rear end, the upper and lower arms17 and 18 are united by a vertically extending portion 20. The lowerarms 18 of each member A are provided with inwardly extending lugs 2121, the lugs on one member A being placed out of alinement with the lugs21 on the other member A, as indicated by the full and dotted lines inFig. 4, so that in assembling or disassembling the gear, the members A Amay be brought closer together and disengaged from the stops. Anysuitable type of gear may be employed and I have shown in the drawing afriction cylinder 22, having an integral rear fol-f lower 23 extendedoutwardly so as to engage the rear stops 12 and rest upon the lowerhorizontal'arms 1818 of the yoke members A A. Mounted within thefriction cylinder 22 are springs 24, friction shoes 25 and spreader 26,which are or may be of any well known construction. A front'follower 27is provided, which is also extended transversely through the open .yokemembers A A and also rests upon the lower arms18-18. The inwardlyextending lugs 21-21, as clearly indicated in Figs. 2 and 3,

serve to support the front end of the friction cylinder 22. p

In order toinsure the proper positioning of the members A A at alltimes, that is, in

their spaced apart relation as shown in Figs. 2 and 3,1 provide spacers28 bolted to I the upper and lower edges of the rear follower 23, eachof said spacers 28 having depending side flanges 29 overlapping thefollower and upwardly extended end lugs 30 which engage the inner edgesof the members A. v

As will be understood, each of the yoke members A is or may be formedfrom a blank by the simple operations of. cutting andstamping, thehorizontal arms- 17 and 18 being turned. to one side of the blank andthe lugs 21 being struck to the opposite side. It will also be notedthat with my improved form of yoke, I avoid the necessity of usingsaddle plates or carry irons since the gear is supported by means of theyoke, which in turn are carried by the stops.

I claim 1. In a device of the character described, the combination'withdraft sills having stops secured thereto, of a yoke, the lattercomprising two members each having outwardly extending flanges adaptedto fit over said stops.

2. In a device of the character described,

the combination with draft sills having front and rear stops securedthereto, of a yoke, said yoke comprising two members each having upperand lower outwardly extended flanges engaging and slidable upon theupper and lower surfaces of said stops.

3. In a device of the character described, the combination with draftsills having stops secured thereto, of a yoke, said yoke comprising twomembers each in the form of a loop and having horizontally extendingupslide upon the upper surfaces of said stops,

each of said members being also provided with inwardly extended lugs atthe bottom thereof adapted to support a gear.

6. In a draft rigging for railway cars, the combination with draft sillshaving stops secured thereto, of a yoke comprising two side members eachhaving outwardly extended upper and lower horizontal flanges andinwardly extending lugs from the bottom flanges, the lugs on one of saidmembers being ofl'set relatively to the lugs on the other member.

7 A yoke for railway draft riggings comprising two members each of'whichis in the form of a loop having upper and lower horizontally extendingarms provided with outwardly turned supporting flanges, a front verticalwall connecting said arms, and a rear vertical portion connecting therear ends of said arms.

8. In a railway draft rigging, the combination with draft sills havingstops secured thereto, of a draw bar, a draft gear, a yoke connected tosaid draw bar, said yoke comprising two spaced'side members engaging andsupported by said stops, and means for holdingthe rear ends of saidmembers in spaced relation, said means comprising spacers secured to theupper'and lower edges of the rear follower of the gear.

9. A yoke for railway draft riggings comprising, two members each ofwhich is in the form of a loop having an outwardly extending projectionalong the upper arm thereof, said projections being adapted to ride uponthe upper faces of stops and be supported thereby.

10. A yoke for railway draft riggings having outwardly extendingflanges. adapted to ride upon the upper faces of stop members andthereby support the yoke.
